Call her up and tell her what to wear, something different, "wear comfortable shoes"
Don't tell her anything more than that.
and then you get an old boom-blaster and bring her to the park, if the weather allows. maybe bring a bottle of wine and something easy to eat, and just chill out with her, dance with her if you can, and just get to know her.
It's even better if the thing you tell her to bring is totally unrelated.
Like "Bring galoshes".
'cause that'll make her go "wtf?...What would I need that for."
And if she brings it, then play around with her a bit. You can pretend you never said anything about galoshes.
Take her mountain-climbing, or something different, something she'll remember.
Like sky-diving.
Last time I took a girl out. We walked aimlessly around town and ended up sitting on a pier in the harbor, eating ice-cream... watching the sun-down, eventually.... and that was it. (K-close and it did spark something: F-close that weekend.)
Nothing fancy, just a $2 ice-cream.
Or ice-skating. that can be fun
And I'll just end this with a line from Sean Stephenson; "Take her out of her element" ... if she's a rich-girl, take her to a monster-truck rally. or if she's a bohemian take her to a fancy restaurant. (The important thing is that you have fun, right ?... just picture an upscale HB's reaction to being brought to a Wrestling Match.)
Be Creative, (or just go for the regular dinner and a movie, a kiss as you drop her off at home, and the "maybe you'll get lucky")
